Abstract

Hand blood flow was measured at rest, with local warming, and with local cooling. Three methods were simultaneously used: water plethysmography (WP), mercury-in-rubber strain gauge plethysmography (SG), and pulsed Döppler flowmetry (D). Of these, water plethysmography is the most sensitive and accurate; strain gauge plethysmography is simpler but less accurate; and pulsed Döppler flowmetry precisely measures instantaneous arterial blood flow without venous occlusion.

摘要

分别在静息状态、局部升温以及局部降温时测量手部血流量。同时使用了三种方法：水容积描记法（WP）、水银橡胶应变计容积描记法（SG）和脉冲多普勒血流仪（D）。其中，水容积描记法最为灵敏和准确；应变计容积描记法更简便但准确性稍差；脉冲多普勒血流仪无需静脉阻塞即可精确测量瞬时动脉血流量。
